Why Is an Auditor Comfort Letter Used?
The primary purpose is to give transaction participants additional confidence in specified financial information. In a securities offering, for example, underwriters may request confirmation that particular financial data included in offering materials agrees with the company's accounting records or has been subjected to specified procedures.
The auditor's communication is tailored to the transaction and the information requested. Its value comes from the auditor's independence and the defined procedures supporting the statements made in the letter.
Companies may encounter comfort letters during initial public offerings, debt offerings, acquisitions, refinancing transactions, or other events where financial information is being presented to external parties.
What Does an Auditor Comfort Letter Contain?
The contents depend on the engagement, transaction, applicable professional standards, and agreement among the company, auditor, and intended recipients. A letter may address selected financial information, subsequent changes, or specific procedures performed by the auditor.
- Specified financial information: Selected amounts or disclosures may be compared with underlying accounting records.
- Procedures performed: The letter identifies the work the auditor performed and the information covered.
- Period covered: Certain procedures may relate to financial information for a defined period or subsequent period.
- Agreed recipients: The letter identifies the parties entitled to rely on the communication.
- Scope and limitations: The wording distinguishes the procedures performed from an audit or broader assurance engagement.
The precise language matters because a comfort letter provides assurance only within the boundaries of the procedures and information expressly addressed.
How Does the Comfort Letter Process Work?
The process usually begins when transaction participants identify the financial information requiring auditor confirmation. The company and its advisers coordinate with the auditor to establish the requested procedures, timing, recipients, and relevant transaction documents.
The auditor then performs the agreed procedures and evaluates the supporting accounting information. Depending on the engagement, this can include comparing amounts in transaction documents with accounting records, reading selected financial information, or performing specified inquiries and analytical procedures.
After completing the work, the auditor issues the comfort letter to the agreed recipients. Because transaction timetables can be sensitive to financial information and closing requirements, coordination between finance, legal, accounting, and transaction teams is important.
How Is an Auditor Comfort Letter Different From Other Finance Letters?
Several financial documents use the term "letter" but serve very different purposes. An Letter Of Credit is a bank-backed payment instrument commonly used in trade transactions, while an auditor comfort letter communicates limited assurance or agreed procedures concerning specified financial information.
A Dunning Letter is a collections communication requesting payment of an overdue receivable. It is therefore part of a credit and collections workflow rather than an external assurance process.
A Management Representation Letter is a written representation provided by management to the auditor during an audit. It supports the auditor's work by documenting management's representations about matters relevant to the financial statements. The auditor comfort letter, in contrast, is issued by the auditor to specified transaction recipients.
What Financial Information Can a Comfort Letter Support?
The information addressed depends on the agreed scope. It may include selected historical financial information, financial statement amounts, changes in certain financial metrics, or other data incorporated into transaction documentation.
For example, suppose a company is preparing a debt offering and its transaction documents contain revenue of $50 million for a specified period. The auditor may perform agreed procedures on that selected amount and communicate the results within the scope of the comfort letter.
This can help transaction participants evaluate whether selected financial information has been appropriately derived from the company's underlying records. The letter should not, however, be interpreted as a general audit opinion on the entire transaction document.
Best Practices for Managing an Auditor Comfort Letter
Companies should begin coordination early enough to allow the auditor to understand the transaction, identify the requested information, and complete the agreed procedures within the transaction timetable.
- Define the intended recipients and permitted use of the letter.
- Identify every financial figure or disclosure requiring auditor procedures.
- Ensure transaction documents and accounting records contain consistent information.
- Maintain supporting schedules and reconciliations for selected financial data.
- Coordinate finance, legal, accounting, and transaction advisers on deadlines and requested procedures.
Clear documentation and consistent source information help the auditor complete the agreed work efficiently and help transaction participants understand precisely what the letter covers.
Summary
An Auditor Comfort Letter is a transaction-related communication from an independent auditor that provides limited assurance or reports specified procedures concerning selected financial information. It is commonly used in securities offerings, financing, acquisitions, and other corporate transactions. Understanding its scope, recipients, procedures, and distinction from an audit opinion helps finance teams coordinate transaction reporting and support informed financial decisions.
